Where these two actually differ
- We flag Seal degradation and water ingress and Band material allergens (dependent on strap type) on the Samsung and not on the Swatch.
- We flag Resin band VOC off-gassing, Resin band degradation over time and Nickel leaching from stainless steel case on the Swatch and not on the Samsung.
- The Samsung is Titanium case, AMOLED display where the Swatch is Quartz crystal, stainless steel case, resin band, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
- We are less certain about the Samsung grade, at 35% confidence against 78%, because it discloses less.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
